Dewar’s have changed the bottle designs for their White Label, 12 Years Old, 18 Years Old and Dewar’s Signature products. You can see the new designs on their website.
According to this article, the new bottles all feature the year 1846, when Dewar’s was founded, the signature of John Dewar and the Royal Warrant mark, which has been awarded to Dewar’s by every British monarch since Queen Victoria.
Dewar’s Whisky senior brand manager, Demetrius Giouzelis, confirmed that the brand “believes in making full, well-rounded whiskies that are enjoyable to drink. It is this well-rounded taste which was the inspiration for our new packaging design’’.
